Abstract

PURPOSE: To prevent easy removal of a cover for illumination by mischief by a method wherein when a cover for illumination is arranged at the opening part of the ceiling of an elevator cage and covered with a rescue port cover, the peripheral edge of the cover for illumination is located between the ceiling and the peripheral edge of the rescuer port cover. CONSTITUTION: To utilize the opening part 4 of a ceiling 3 as a rescue port, a lock tool 8 is first removed and a rescue cover 16 is opened upward around a fitment 7 serving as a fulcrum. One side of a cover 9 for illumination is then pushed up and the cover 9 for illumination is brought into an oblique state. By pulling out a peripheral edge part 9a on the other side to the opening part 4 side, the cover 9 for illumination is taken out. The opening part 4 released in this way is utilized as a rescue port. The cover 9 for illumination has the peripheral edge 9a brought into a position relation to be overlapped with the peripheral edge part 16a of the rescue cover 16 and the peripheral edge part 16a performs a role of a stopper, whereby the cover 9 for illumination is not easily removed from the cage side.

【Example】

Example 1. FIG. 1 is a cross-sectional view showing an embodiment of the present invention, in which the same or corresponding parts as those in FIGS. 5 and 6 are designated by the same reference numerals and the description thereof is omitted. In the figure, reference numeral 16 is a rescue exit cover whose peripheral portion 16a is mounted on the cushioning rubber 11 which is an elastic body, and the peripheral portion 16a and the peripheral portion 9a of the lighting cover 9 are partially overlapped with each other. There is.

In the above ceiling lighting device, in order to use the opening 4 of the ceiling 3 as a rescue exit, the stopper 8 is first removed, and the rescue cover 16 is opened with the metal fitting 7 as a fulcrum.
Next, the lighting cover 9 is easily removed from the ceiling 3 by pushing up one side of the lighting cover 9 to make the lighting cover 9 oblique, and pulling out the peripheral edge portion 9a on the other side toward the opening 4 side. Thus, the opening 4 can be used as a rescue exit.

Further, even if the user of the elevator tries to remove the lighting cover 9, the peripheral edge portion 9a thereof is in a positional relationship of overlapping with the peripheral edge portion 16a of the rescue outlet cover 16, and the peripheral edge portion 16a serves as a stopper. Therefore, the lighting cover 9 cannot be easily removed from the ceiling 3. Further, the lighting cover 9 and the rescue exit cover 16
Since the cushioning rubber 11 is interposed between and, the rescue outlet cover 16 will not be damaged even if an operator rides on the rescue outlet cover 16 and a load is applied to the rescue outlet cover 16.

Example 2. 2 is a sectional view showing another embodiment of the present invention, FIG. 3 is a sectional view taken along the line III-III of FIG. 2 (metal fittings and stoppers are omitted), and FIG. 4 is a perspective view of the detachment preventing means of FIG. Reference numeral 19 denotes a lighting cover having notches 19a formed on both side edges, and 12 is a detachment preventing means for suspending the illumination cover 19 from the ceiling 3 so as to prevent the illumination cover 19 from coming off the ceiling 3. The prevention means 12 includes a column 12a, a stopper 12b having an end attached to the upper end of the column 12a, a handle 12c attached to an intermediate part of the column 12a, a stopper 12b, and a lighting cover 19 in general.
A spring (not shown) for urging the stopper portion 12b so that and are overlapped with each other, and a detent pin 12d.

In the case of this embodiment, the stopper portion 12b and the notch portion 19a of the illumination cover 19 are usually overlapped by the elastic force of the spring, and the stopper portion 12b serves as a stopper. As a matter of fact, the lighting cover 19 cannot be easily removed from the ceiling 3. Further, the handle 12c is rotated by 180 ° so that the stopper portion 12b and the lighting cover 19 do not overlap each other, and then the stopper 8 is removed, and the rescue outlet cover 6 and the lighting cover 19 are rotated by 90 ° with the metal fitting 7 as a fulcrum. By rotating, the opening 4 can be used as a rescue exit.
The cutout portion 19a is not always necessary.

[0019]

As described above, according to the ceiling lighting device of the present invention, the lighting cover is arranged so that the peripheral edge of the lighting cover is interposed between the ceiling and the peripheral edge of the rescue outlet cover. Since it is provided, even if the lighting cover is to be removed, the peripheral edge portion of the rescue outlet cover acts as a stopper, and it is possible to prevent the lighting cover from being removed or stolen.

Further, claim 2 or claim 3 of the present invention.
According to the ceiling illuminating device, the illuminating cover is prevented from being easily removed from the ceiling, and the same effect as that of the first aspect of the invention can be obtained.

Further, according to the ceiling lighting device of the fourth aspect of the present invention, since the elastic body is interposed between the peripheral portion of the rescue outlet cover and the ceiling of the first aspect of the invention,
Even if a load is applied to the rescue cover, the elastic body cushions the load, and damage to the rescue cover due to the load is prevented.
